440 six pack kickdown linkage identification

[QuebecRollin]

I purchased a partially finished 69’ coronet R/T over the winter that came with a fresh engine build and included a cast iron six pack intake and a set of 340 Six Pack carbs as well as a bunch of linkage in a box.
I have no idea if any of the linkage that was in the box is actually correct for the six pack setup.

Does anyone know where to find the measurements to identify the different linkages so I can figure out if I have what I need?

I did order a new linkage set from A&A but it is on backorder.

I have the correct intake bracket but that’s about all that I can confirm as being the correct part for the six pack application.
I ditched the Cast manifold and 350 carb in favor of a Fitech six pack and an Edelbrock manifold.

If I can’t figure out the correct rods and levers my other option is a Lokar kick down cable that I have in the shop.
I have no experience with the cables and my understanding is they are not the greatest so I’d like to try to stick with stock.

Here is a picture of what I got in the parts box.

I would think that from the trans up to the throttle cable bracket would be standard. Not sure from there to center carb arm. You have the better part of it to the carb. I have no idea what the Fitech set up needs. There's another member here that has done it. He has the running Road Runner avatar, I think.
